How do I maintain safety while decorating under-stairs space?

Maintain safety by keeping walkways clear, preserving natural light, and avoiding tripping hazards in under-stairs areas. Use lightweight, low-profile decor accessible from the stair edge, avoiding bulky furniture or items that block sightlines. Ensure good lighting and leave negative space to prevent crowding. If storage is needed, consider a hidden door from an adjacent room to keep the stair side open and hazard-free.
